Dark Matter Day at SNOLAB

DMD 2019 
















There is much more to the universe than we can see. In fact, we are only seeing about 5% of it! The remainder is comprised of dark matter and dark energy. 

Dark Matter Day is an initiative of the Interactions Collaboration, a global group of particle physics communicators, that aims to shine a light on this mystery and on the work of scientists to understand this silent, unseen, and massive presence in our universe.  

On and around October 31, 2019 when the world celebrates the historic hunt for the unseen, SNOLAB will be no exception. We are organizing dark matter day events and activities over the month of October. Find something that interests you from the list below and attend an event in person or join us online. Be sure to check back often for surprise events and mystery guests!  

Don't be afraid of the dark; follow along and connect with us on Facebook, Twitter and Instagram @SNOLABscience.



Dark Matter Pumpkin Search at Dynamic Earth

Dark Matter Day Activities at the Sudbury Market

Dark Matter Day is coming up on October 31st! Here at SNOLAB, we're on the hunt to be the first to detect dark matter. Scientists from around the world work deep underground in our lab trying to detect these mysterious particles. Join us to learn more about dark matter with a family-friendly dark matter scavenger hunt at the market! 

WHEN: Saturday, October 26th from 10:00 am - 1:00 pm

WHERE: CP/VIA Rail Station on Elgin Street, Sudbury ON

Dark Matter Lesson Plans

► Classroom Kit: This grade 11 and 12 classroom kit from Perimeter Institute can be downloaded in English or French, free of charge from the Perimeter website. The kit provides teachers with print and digital resources to support hands-on, student exploration of concepts related to gravity and orbital motion, gravitational lensing, measuring mass of galaxies, and theories of dark matter.

Lesson Plan:  In this lesson plan from Sonoma State University students in grades 9-12 will learn about dark matter how scientists are trying to detect this matter that is not visible.  In the lab activity students will use several methods to determine what "hidden matter" lies between two paper plates.

Dark Matter TedED Lessons

► How to build a dark matter detector:  More than 2 kilometers below the surface of northern Ontario, suspended in 345,000 liters of ultra-pure water, there’s a perfect sphere. Scientists continuously monitor this chamber, looking for a glimmer of light in the darkness. Why? Because that light would indicate the presence of one of the universe’s greatest mysteries: dark matter. Jenna Saffin describes how this dark matter detector works.

Dark Matter: The matter we can't see:  The Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy) and how we might go about detecting it.

Shedding a light on dark matter:  Physicist Patricia Burchat sheds light on two basic ingredients of our universe: dark matter and dark energy. Comprising 96% of the universe between them, they can't be directly measured, but their influence is immense.

Could we Create Dark Matter:  Eighty-five percent of the matter in our universe is dark matter. We don’t know what dark matter is made of, and we’ve yet to directly observe it, but scientists theorize that we may actually be able to create it in the Large Hadron Collider, the most powerful particle collider in the world. So how would that work? CERN scientist Rolf Landua explains how to discover a new particle.

Dark Matter Video Games

► Created to accompany the Perimeter Explorations "Mystery of Dark Matter" classroom kit, this video game challenges students to apply what they've learned as they add stars, planets, and black holes to a galaxy.
